Megalithic Tombs
What sits in a flat stretch of pasture at Knockadoo is not one megalithic tomb but what appears to be two, arranged as a pair of stone chambers set roughly 3.6 metres apart.
Most megalithic tombs present themselves as a single structure, however ruined. This site is different, and that difference is what makes it quietly arresting for anyone who pauses long enough to read the ground.
The two groups of upright stones, known as orthostats, each seem to represent a separate burial chamber. The south-western group consists of four stones: two uprights set facing each other, 1.75 metres apart, with a lower stone placed transversely between them. This transverse stone is likely a sillstone, a threshold or partition element commonly found in megalithic architecture, sitting here at around 0.5 metres high. A further orthostat to the west of this group appears to be a sidestone, suggesting the chamber once had defined walls. The north-eastern group is arranged on a polygonal plan, measuring roughly 2.3 metres north to south, with single uprights positioned at the north, east, and south. Several other stones lie prostrate or are partly hidden in the turf. Around the southern side of each chamber, faint traces of a mound survive, the last visible remnant of the earthen covering that would originally have enclosed the whole structure. The site was catalogued by Seán Ó Nualláin in his 1989 survey of the megalithic tombs of County Sligo, which placed it as entry number 90 in that county's record.
